打印未显示在 ipython 笔记本中 [英] Print not showing in ipython notebook

问题描述

我正在使用 ipython 笔记本 (http://ipython.org/notebook.html) 做一个演示，似乎打印功能不起作用:

I am using ipython notebook (http://ipython.org/notebook.html) to do a demo and it seems like the print function is not working:

为了清晰起见，上图中的命令在此处重写.

The commands in the above picture are rewritten here for clarity.

In [1]: 'hello world'
Out [1]: 'hello world'

In [2]: print 'hello world'

简而言之，[2] 没有打印输出.

In short, there's no print output from the [2].

有谁知道这是否是一个已知的错误?有谁知道如何修复它?

Does anyone know whether it's a known bug? And does anyone know how to fix it?

推荐答案

当我的第一个代码单元是:

I had a similar printing problem when my first code cell was:

import sys
reload(sys)
sys.setdefaultencoding("utf-8")

然后我像这样评论了第二行和第三行:

Then I've commented the second and third lines like this:

import sys
#reload(sys)
#sys.setdefaultencoding("utf-8")

重置内核并重新运行程序，现在我的打印语句可以正常工作了.

Reset the kernel and re-ran the program and now my print statements are working properly.

后来，我发现当我第一次遇到打印问题时，所有打印输出实际上都被发送到 ipython 控制台终端(在我的 Linux 机器上)，而不是被嵌入到笔记本中.

Later on, I've found that when I was first having the printing problem, all print outputs were actually being sent to the ipython console terminal (on my Linux box), instead of being embed on the notebook.
